Amazing facts in Basic Science

Cranberries - Len Academy

Ripe cranberries will bounce like a ball. For this reason, they are nicknamed 'bounceberries'. They will also float in water

Tomatoes and Avocados are fruits, not vegetables

Sweat in itself doesn't smell. The smell that accompanies sweat is actually caused by the presence of bacteria on your skin. This bacteria breaks the sweat coming out of your sweat pores down into acids, thus making it smell.

Deodorants contains alcohol and are antibacterial. They work by killing the bacteria that makes sweat smell

Ice cubes made with fresh water are white in color while those made with boiled water are crystal clear

Cats are unable to taste sweet things

Apples float on water. Other fruits that float on water include lemons, bananas, pears, and oranges

Rain water is said to be pure because it's colorless, odourless and tasteless. Interestingly, it also contains vitamin B12.

Vitamin B12 is an important nutrient that keeps the blood cells and neurones healthy. It also assist in building the DNA (a genetic material present in the cell's nucleus). Vitamin B12 also aid in the prevention of megaloblastic anemia which makes people weak and tired

Rasceta is the name given to the lines on your palm


NOTABLE POINTS IN Basic Science

The uniqueness of man can be defined as that which makes man distinct from every other animal and living organism.

Humans are higher animals when compared to other animals.

Under the classification of living organisms, humans belong to an order termed primates and thus share the same characteristics (as primates). In addition to these features, they also have their unique characteristics.

Wastes can be classified into various types. These are:

  • Biodegradable waste

  • Non-Biodegradable waste

  • Refuse

  • Sewage

  • Recyclable waste

  • Electronic waste

  • Green waste

  • Biomedical waste

Disaccharides are composed of two monosaccharides joined together; thus are also referred to as double sugars.

Disaccharides are often added as sweeteners to food; for instance, the table sugar called sucrose is a disaccharide often used by us to sweeten our tea.

Maltose is another disaccharide used as an ingredient for making malt drinks, chocolates and candies.

The breast milk contains the disaccharide -> lactose.

Lactose is very vital for the normal growth and development of infants.

In adults, disaccharides are non essential nutrients. This implies that we can live without them as adults.

Below is a summary of monosaccharides that make up disaccharides (double sugars).

  • Maltose = Glucose + Glucose

  • Lactose = Glucose + Galactose

  • Sucrose = Glucose + Fructose

Other examples of disaccharides include trehalulose and isomaltulose
